Abstract [en]

The thesis is a case study in which a survey is carried out on why the actual result exceeds production estimate of construction projects and how the site management can affect the outcome.

The aim is to highlight the importance of a well-functioning site management and the importance of obtaining accurate calculations in order to keep the budget in a construction project.

This is achieved through a case study where economic deviations are identified and causes of these sets. The causes of deviations were categorized as follows:

Calculation errors

Account error

Change in method

Option

Management

The results obtained show that the major cause of deviations is due to miscalculation, followed by the change in method. The biggest single cause was identified as costing systems form, which is used in casting of concrete. The average cost increased by 340% which resulted in a miscalculation by 870 000:-. Furthermore was determined that the site management has the authority to affect the total deviations of a construction project by about 40%.

Summary of the interview, which was conducted for the site management on the projects audited shows that the biggest cause of deviations is the lack of planning.

The recommendations given are to be consistent in posting, so that the right cost is at the correct account, it simplifies reconciliation and predictions. Working for a dynamic group where there are leadership skills, administrative skills and build technical knowledge.
